摘 要:通过对再生骨料取代率为70%的钢筋混凝土板和普通钢筋混凝土板的试验比较,研究了再生混凝土板在受荷载作用下的破坏形态。试验结果表明,再生混凝土板与普通混凝土板的破坏过程相似,且在相同配筋率情况下,再生混凝土板的承载能力和变形与普通钢筋混凝土板大致相当。因此,根据GB 50010—2010《混凝土结构设计规范》提出的普通混凝土计算公式也适用于再生混凝土,并且具有较高的安全储备。
Abstract: Compared reinforcement of 70% recycled aggregate concrete with the ordinary concrete plate, the damage form of recycled concrete plate is studied under the load, the results show that the failure process of recycled concrete plate is similar to ordinary concrete plate, under the condition of the same reinforcement ratio, the bearing capacity and deformation of recycled concrete are similar with ordinary concrete plate. According to the GB 50010—2010 Concrete Structure Design, the concrete formula can also be applied to recycled concrete, and has high security reserves.
